Display-message troubleshooting Note The following tables explain the messages that might appear on the control-panel display or in the event log. Alphabetical printer messages and their meanings are listed in "Alphabetical printer messages" on page 258, and numerical printer messages are listed in "Numerical printer messages" on page 274. Not all messages are described in the tables; the messages that are not listed are self-explanatory. Note Status messages Status messages reflect the current state of the printer. They inform you of normal printer operation and require no interaction to clear them. They change as the state of the printer changes. Whenever the printer is ready, is not busy, and has no pending warning messages, the status message READY appears if the printer is online. Warning messages Warning messages inform you of data and print errors. These messages typically alternate with READY or with status messages and continue to appear until the SELECT ( ) button is pressed. If CLEARABLE WARNING is set to JOB in the printer's configuration menu, these messages are cleared when the next print job is sent to the printer. Error messages Error messages inform you that an action must be performed, such as adding paper or clearing a paper jam. Some error messages are auto-continuable (these are not critical errors and the printer will continue to function). If the printer setting AUTO CONTINUE=ON is used, the error message will continue to appear for about 10 seconds and then the printer will resume printing. Pressing any button while an auto-continuable error message appears on the control-panel display overrides the auto-continue feature, and the button's function will take precedence. For example, pressing the CANCEL JOB button will cancel the job. Critical-error messages Critical-error messages inform you of a device failure. Some of these messages can be cleared by turning the printer off and then on. These messages are not affected by the auto-continue setting. If a critical error persists, then service is required.
